Remove the jQuery dependency

This branch will go live in 1.0.0 and will completely remove the jQuery dependency from the core library. It will add a `jquery.card.js` file that will maintain the same API.

TODO:

* [ ] replace [`jquery.payment`](http://github.com/stripe/jquery.payment) with a jQuery free version
* [ ] remove jQuery from core Card library and restructure API
* [ ] create `jquery.card.js` that maintains the same API as `0.0....` versions
* [ ] update documentation for new core library and jQuery API
